T0 all whom, t may concern:

Be it known that I, AUSTIN SNEERINGER VOGT, a citizen of the UnitedStates, residing at Tyrone, in the county of Blair and State ofPennsylvania, have invented a new and useful Lock, of which thefollowing is a speciication.

My invention relates to locks of the barreland-tumbler type, and has forits object to provide a lock of this class wherein a knob is attached toand is movable only with the barrel, said knob being provided with akeyhole for the reception of the tu mbler-adj usting key, whereby whenthe key is in place it is rotatable with the knob and without specialmanipulation to withdraw the bolt of the lock.

A further object of the invention is to so construct the mechanism of abarrel-andtumbler lock as to provide for shifting the barrel to renderthe tumbler or barrel looking mechanism inoperative, whereby the barrelis turnable by means of an attached knob without the use of a tumblersetting or adj usting key. i

A further object of the invention is to provide a second knob for themanipulation of the bolt, which is movable, to retract the boltindependently of the barrel-carried knob,said second orindependently-movable knob being capable of a plurality of revoluble orangular adjustments with relation to the barrel and having attachedthereto the bolt-operating lug or segment whereby the angular adjustmentof said lug or segment or the extent of swinging movement thereof aboutthe common axis of the barrel and the barrel-carried knob as a centermay be varied by turning the independently-movable knob.

A further object of the invention is to provide means whereby theindependently-movable knob is normally locked against accidentalmovement or movement independent of the barrel, but is releasable by themanipulation of means Within reach of a hand grasping said knob.

A further object of the invention is to provide means whereby theindependently-movable knob may be locked against movement and the barrelmay be looked, independently of its tumblers, to prevent themanipulation of the bolt by means of the barrel-carried knobeven withthe aid of a tumbler adjust'- ing or setting key, without interferingwith the operation of the lock by means of the inner 'orindependently-movable knob, and also to provide such locking means,independent -of the barrel-locking tumblers, as will secure the boltagainst movement, independently of the barrel, to prevent the repressionof the bolt by the direct application thereto of a tool outside of thelock and its coperating members.

A further object of the invention is to provide a reversible lock of theclass named whereby without change of construction the same may beapplied to either a right or a left hand door, and also to provide meanswhereby the parts may be reversed to suit the direction of swingingmoveme'nt of a door while maintaining the knobs respectively at thedesired sides of the plane of the door or, in other words, with thebarrel-carried knob at the outside of a house or room door.

Further objects and advantages of this invention will appear in thefollowing description, and the novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a perspective View of a lock constructed inaccordance with my invention, viewing the same from the outside or thatside at which the barrel-carried knob is arranged. Fig. 2 is ahorizontal section taken in the plane of the axis of the barrel. Fig. 3is an elevation of the lock with 4the face-plate omitted and the barrelin section.

Similar reference characters indicate corresponding parts in all thefigures of the drawings.

In the drawings I have illustrated my invention in connection with amortise-lock, wherein 2O represents the lock-casing fitted in a mortisein the door, which is indicated in section at 2l, said casing having aremovable face-plate 22, a guard-plate 23, which is secured against theedge of the door, and at its rear end a plurality of marking-spurs 24,of which two are shown arranged adjacent, respectively, to the upper andlower sides of the casing. Each of these spurs or pins is located sothat its pointis at equal distances from three adjacent edges orsurfaces of the casing. For instance, the upper spur is arranged withits point at equal distances from the upper surface and from theopposite side surfaces of the casing. Therefore in marking a door forlthe reception of lthe lock-casing it is only necessary to place the endof the case Where it is desired to arrange the lock, and by pressing thespurs into the wood the exact loca-tions for the center of a bit to beused in making the ends of the inortise are indicated. Obviously, afterboring the two end holes, of which the centers are indicated, the outersides of said holes marking the extremities of the mortise and the widththereof being equal to the thickness of the easing, the intermediatematerial may be removed as in the ordinary practice.

One of the side walls of the casing, and preferably the removableface-plate 22, is provided with an opening 25 for the reception of theadjacent end of the barrel-casing 26, said opening being ofirregularcontour and the adjacent end of the barrel-casing being ofcorrespending contour, whereby the lock-casing is adapted to occupyeither of two positions with relation to the barrel-casing, saidpositions being at an angular distance of one hundred and eightydegrees. In other words, the interlocking connection between thelock-casing and the barrel-casing is such as to provide for thearrangement of the lock-easing in either of two diametrically oppositepositions with relation to the barrel-easing, and' in the constructionillustrated this relation is effected by flattening the opening 25 atdiainetrically opposite points and correspondingly attening the adjacentend of the barrel-casing, said iiats being adapted to register in eitherof the said positions of the lock-casing with relation to thebarrel-casing. This adjustment of the lock-casing provides for adaptingthe device for use in connection with either a right or a left handdoor.

Arranged within the lock-easing is a boltyoke having spaced arms 27terminating at their inner ends in opposite inturned ears 28, which areoiiset from the planes of the arms 27 at one side or are of lessthickness than said arms,for a purpose hereinafter explained,l said earsbeing located adjacentto a bolt-stem opening 29 in the lock-casing, saidbolt-stem opening being arranged in registration withthebarrel-casingopening25. Saidyoke-arms are connected at their outerends bya transverse bar 30, to which is attached the bolt head or nose3l, operating in a bolt-opening 32 in the guard-plate 23. The means ofattachment of the bolt head or nose tothe cross-bar 30 is such as toallow the former to be reversed in position,whereby the bevel thereofmay be arranged toward either side wall of the lock-casing, and in theconstruction illustrated the means of attachment consists of a screw 33,whereby upon loosening the screw the bolt head or nose may be turned toadapt the lock to be applied to either an inwardly or outwardly swingingdoor. Also the arms 27 of the yoke are connected bya second crossbar 34,through which extend guide-pins 35, attached at their rear ends tosuitable brackets secured within the lock-casing, and coiled upon theguide-pins are bolt-actuatingsprings 37, which bear at their outerextremities against the cross-bar 34, and thus yieldingly hold the boltextended or in its locking position. The removable face-plate 22 issecured in place by means of screws 3S, engaging lugs or posts 39 withinthe lock-casing, and other screws 40, extending through the lock-casingfrom the opposite side, engage the barrel-casing 2G to secure the latterin the desired position or with the lock-casing at the desiredadjustment with relation to the barrel-easing. Obviously the openingswith which the screws 40 engage must be at an interval correspondingwith the angle through which the lockcasing may be adjusted withrelation to the barrel-casing to insure the proper engagement thereofwith the barrel-casing in bot-h positions. The screws 40 may beintroduced after the arrangement of the lock-casing and barrel-casing tosecure said parts together by passing them through gimlet or augeropenings 40*rt in the door. (Indicated in dotted lines in Fig. 2.)

In the barrel-casing is mounted a revoluble barrel 41, carrying a knob42, which in the ordinary use of the lock will be arranged at theouterside ofthe plane of the door to which the lock is attached, and Ipreferably attach the knob directly to a stein 43, which is integralwith the barrel, a collar 44 also being formed upon said stem to iit ina seat formed in the outer end of the barrel-casing, and a flange 45being formed at the outer end of the stem for attachment to a grip-ringof wood or other suitable material, constituting the knob 42. Vthile Iprefer to construct the body portion of the knob of annular shape, togive access to the end of the barrel-stem, in which is formed a keyhole4G, it will be understood that this feature is susceptible ofmodification without departing from the essential construction of abarrel-carried knob provided with a keyhole for the reception of atumbler adjust- IOO IIO

ing or settin g key 47, which is adapted to turn With the knob, afterproper insertion, in the manipulation of the lock.

The barrel is provided beyond the inner end of the barrel-casing with aspindle or stem extension 48, terminally threaded for engagement with aremovable barrel-n ut 49, and this barrel-nut secures, in operativerelation with the barrel and its spindle or stem extension, a sleeve 50,carrying a bolt-operating lug 5l of segmental construction, which isinterposed between and is in operative relation With the ears 28, thefunction of said lug being to impart motion to the bolt to withdraw itWithin the lock-casing. Said sleeve also carries a iiange 52, which isseated upon said ears 28 or in contact with the offset faces thereof, asshown clearly in Fig. 4. The inner end of the barrel projects into thelockcasing beyond the inner end of the barrelcasing, as shown in saidFig. 4, and the sleeve 50 is counterboredito receive the same, saidsleeve being adapted for rotary movement independently of the barrel.

The sleeve 50 forms the body portion of the stem ofan inner knob 53, orthat knob which is ordinarily arranged at the inner side of the door ofa building or apartment, said knob having a cuff 54 fitted exteriorlyupon the sleeve and secured thereto by means of screws 55 or equivalentdevices. Thus, when otherwise unaifected, the sleeve 50, by means of theknob 53, may be turned upon the barrel and independently thereof toWithdraw the bolt in opposition to the actuating-springs of the latter.It is desirable, however, for reasons which will be apparent as thenature of my invention is more fully disclosed, to lock theindependently-movable knob normally in a ixed relation to the barrel,and hence I employ a clutch 56, consisting of a collar mounted for axialsliding movement with relation to the sleeve 50, and spaced pins 57,arranged parallel with and preferably at opposite sides of the barrelspindle or extension, said pins extending through suitable guides 58 inthe sleeve and projecting into the counterbore at the inner end of thelatter for engagement with sockets 59, formed in the extremity of thebarrel, said clutch being yieldingly held in engagement with the barrelto lock the independentlymovable knob in a iixed relation to thebarrel-carried knob by means of a spring GO, which is coiled upon thenut 49 and bears at its extremities respectively against the clutch 56and a shoulder formed by an enlargement or head 6l of the nut. Assuming,however, that the barrel is locked against rotary movement and it isdesired to operate the lock by means of theindependently-movableknob,Ihaveprovided the clutch 56 with a radial gripor ear 62, extending outwardly through a longitudinal slot 63 in thecuff 54, Where it is Within reach of the tinger of a hand grasping saidinner knob to provide for the disengagement of the clutch (to releasethe inner knob) andthe turning of the knob practically in one operation.The nut 49 is secured against displacement by means of a transverse pin64, which extends transversely through 'the barrel-spindle or stemextension 48.

The tu mbler mechanism of the lock embodying my invention is analogousin some respects to that of similar mechanism in locks heretoforedevised in that the barrel is provided with a number of radial openings65, arranged in a longitudinal series for the reception of barrel orsetting pins 66, said barrel-pins communicating at their inner ends Witha key-seat which consists of a prolongati'on of the keyhole 46 at theouter end of the barrel, as hereinbefore described, and thebarrel-casing is provided with a corresponding series of openings 67,adapted to register, respectively, With the barrel-openin gs 65, andhave arranged therein the tumblers 68, with their actuating-springs 69,said openings being closed at their outer ends to form bearings for theadjacent extremities of the springs by means (not shown) which when thelock is set up for use must be secured against displacement, as will beunderstood by those skilled in the art to which my invention appertains.The coperatin g or registering setting-pins and tumblers 66 and 68, asin the ordinarypractice, are of complemental lengths, and the key 47, ofwhich the blade may be corrugated, as illustrated, is provided with anedge contour suitable for adjusting the setting-pins 66 so as to removethe spring-actuated tumblers 68 from engagement with the barrel openingsor sockets 65, and thus allow the rotation of the barrel within thebarrelcasing. The key which I employ, however, is provided with alateral tongue 7l, extending in the opposite direction from thepin-operating edge and adapted to traverse a longitudinal channel 72,formed in the inner surface of the barrel-casing, said channel at itsinner end communicating with one end of a cross or segmental channel 73,of which the length determines the extent of angular or turning movementof the barrel-carried knob in the operation ot the bolt, or, in otherWords, limits the movement of the barrel, said crosschannel terminatingin abrupt walls forming stops arranged in the path of the key-tongue 7l.At the opposite end from the longitudinal chan nel 72 the transverse orcross channel 73 communicates with the inner end of a secondlongitudinal channel 74,Which,in common with the channel 72, extends tothe outer end of the barrel. Thus to operate the lock by means of theouter or barrel-carried knob it is necessary to insert the key into thekeyseat to adjust the setting-pins 66, the tongue 7l of the keytraversing the channel 72 to the inner end thereof. While the keyremains in place the knob may be turned through an arc equal to thelength of the cross-channel 73; but after the knob has been turnedthrough said arc the key may be withdrawn by causing the tongue 71thereof to traverse IOO IIC

the second-named channel 74 for a purpose hereinafter explained.

In addition to the tumblers GS the barrelcasing is provided with aseries of cushionpins 75, actuated by springs 7G, said cushionpins beingarranged diametrically opposite the second or outlet channel 74:, withthe object of allowing the outward movementof the setting-pins 66 duringthe removal of the key from the key-seat, the barrel being located withthe tongue 7l in alinement with said outlet-channel 74. It will beunderstood that these cushion-pins are designed to allow thesetting-pins to move outward as the key is withdrawn from its seat, andthey serve as convenient means for returning said settingpins to theirnormal positions within the barrel to prevent the setting-pins fromremaining extended beyond the barrel-surface, and thus interfering withthe subsequent turning of the barrel; but it is obvious also that othermeans may be employed for thus allowing the outward yielding of thesetting-pins during the withdrawal of the key from its seat. rlhecushion-pins 75 are preferably of larger diameter than the setting-pinsand also than the tumblers, and hence said cushion-pins will not enteror engage with the guideways or openings 65, in which the setting-pinsoperate when the barrel is turned to aline the same. The tumblers andcushion-pins are preferably arranged at an interval of ninety degreesfrom each other, and the length of the limiting transverse channel 73 isalso ninety degrees, whereas the extent of angular movement of thebarrel necessary to withdraw the bolt from its engaging to itsdisengaging position is less than ninety degrees.

As hereinbefore described, the manipulation of the lock by means of thebarrel-carried knob can be accomplished only by communicating motion tothe sleeve forming the spindle of the independently-movable knob, theclutch 56 being employed to connect the barrel and said sleeve normallyfor simultaneous movement. It is desirable at times to so arrange theparts that the lock may be operated from either side without the use ofa key, or, in other words, that the lock may perform the ordinaryfunctions of a latch, whereby the door may be opened from either sidesimply by turning the adjacent knob. To adapt the mechanism to performthis function, I so construct the parts as to adapt the barrel to occupyeither of two positions with relation to the lug or segment carryingsleeve 50, said positions being approximately at an angle of ninetydegrees to each other. As above described, the clutch 5G is providedwith pins 57 for engagement with sockets 59 in the barrel, theengagement of said pins with the sockets 59 being designed to maintainthe barrel and lug or segment carrying sleeve in their normal positions,when the barrel may be locked by means of the tumblers G8, and the useof the key is necessary in order to release the barrel. The barrel,

however, is also provided upon a line approximately at an angle ofninety degrees to a line connecting the sockets 59 with auxiliarysockets 59, with which said pins 57 may engage to secure the barrel andsleeve in their adjusted relative positions. The relation between theparts is such that the pins 57 cannot accidentally engage the auxiliarysockets 59, for the reason that when `the clutch is disengaged from thebarrel to release the inner or independently-movable knob and said knobis turned to withdraw the bolt the pins 57 do not come into registrationwith the auxiliary sockets, for the reason that the angular intervalbetween the sockets 59 and 59"L is greater than that throwr of the knobwhich is necessary to withdraw the bolt, the former being approximatelyninety degrees, while the latter is somewhat less than ninety degrees.When, however, it is desired to adjust the parts to perform the functionof a latch, the clutch 5G is withdrawn to disengage its pins from thesockets 59, and the key having been fitted in its seat to adjust thesetting-pins GG the barrel is turned until the tongue 71 of the keycomes in contact with the limitingstop, and hence into alinement withthe outlet-channel 74, whereupon the key is withdrawn, and pins 57 areallowed to engage the auxiliary sockets 59, with which they are then inregistration, to lock the barrel in its new or adjusted position withrelation to the lug or segment carrying sleeve. Obviously this angularadjustment of the barrel disposcs the tumbler-openings 65 out ofregistration with the tumblers, and the movement of the barrel necessaryto withdraw the locking-bolt is insufficient to return the openings 65to registration with the tumblers G8, and hence the barrel cannot becomelocked in the barrel-casing while the barrel and inner knob occupy theiradjusted relative positions. Toreturn the parts to their normalpositions, it is necessary only to disengage the clutch 5G from thebarrel and turn the latter to cause registration of the sockets 59 withthe clutch-pins'57, thereby arranging the tumbler-openings G5 inregistration with the tumblers. Thus by a simple relative arrangement ofparts I am enabled to Vary the adjustment of the barrel with relation tothe latch mechanism, (consisting of the bolt and means for withdrawingthe same,) whereby the device embodying my invention is adapted toperform the functions of either a lock or a latch while having theadvantages of the barrel-locking means and the barrel-carried knob.

It will be understood from the foregoing description that when thebarrel and the lug or segment carrying sleeve 50 are locked in theirnormal relative positions the barrel can be turned only when the properkey occupies the seat 4:6 and that owing to the stop-tongue 7l, which iscarried by the barrel when the key is seated, the barrel can be turnedonly through a limited angle., and hence in one di- IOO IIS

rection from its normal position. other hand, when theindependently-movable knob is released from the barrel it may be turnedin either direction to withdraw the bolt, owing to the tact that thebolt-yoke is provided with opposite ears 28 and the sleeve 50 with abolt-opening lug or segment 5l., of which the extremities are arrangedapproximately in contact, respectively, with said ears 28, the length ofthe lug or segment 5l being preferably equal to the interval between theears to avoid lost motion or play in the lock. I utilize this relationbetween the parts to provide for locking the barrel-carried or outsideknob positively against movement to retract the bolt even by the aid oithe tumblersetting key, while allowing the inner orindependently-movable knob to be turned to open the door from theinside. To accomplish this, I mount upon the lug-carrying sleeve 50 alocking-slide 77, carrying a locking-lug 78, which normally occupies aposition in the plane of the flange 52, the latter being cut away forits reception, as shown clearly in detail in Fig. 9; The slide may bemounted in any suitable manner upon the sleeve, as by cross-sectionallydovetailing the same to iit a corresponding longitudinal guide in thesleeve, and at that extremity adjacent to the knob the slide is providedwith an outwardly-extending grip or knob 79, adapted to operate in aslot 8O in the cuff 54. The locking-lug 78 is located at an intervalfrom the adjacent end of the bolt-operating lug or segment 5l, which isequal to the Width of the adjacent yoke-ear 28, whereby said ear isadapted to snugly tit between said lugs 78 and 51, said ear normallyoccupying a position between the transverse planes of said parts, asindicated in Fig. 5; but said lug 78 when in its normal positionoccupies a position in the longitudinal plane of the flange 52, andhence outof the longitudinal path of the ear 28, whereby the bolt isfree to operate and may be withdrawn by turning the sleeve in eitherdirection, as hereinbefore explained. By adjusting the slide, however,to arrange the lug 78 in the longitudinal plane of lthe ear 28 or in thepath thereof, whereby said ear is arranged snugly between saidlocking-lug 78 and the adjacentend of the bolt-operating lug or segment5l, the bolt-operating lug can be swung toward the lug 78 to withdrawthe bolt, but cannot be turned in the opposite direction, and hence thebolt cannot be withdrawn by means of the barrel-carried knob, for thereason that the limiting devices by which the direction of movement ofthe barrel is controlled prevent the turning of the barrel in any otherdirection than that which would .cause said bolt-operating lug orsegment to move away from the lug 78, or, in other words, which wouldcause said lockinglug to press forward against that ear which isinterposed between the lug 78 and the adjacent end of the bolt operatinglug 5l. Therefore when the locking-lug 78 is in the On the adjustedposition above mentioned, in the plane of the yoke-ear 28, the outer orbarrelcarried knob is positively locked against movement irrespective ofthe tumblers, and hence cannot be turned to operate the bolt even whenthe proper key is inserted to set the tumblers. On the other hand, thelock may be manipulated by means of the inside knob, for the reason thatby disengaging the clutch 56 from the adjacent end of the tumbler saidinner or independently-movable knob may be turned in the oppositedirection or in that direction which Will carry the boltoperating lug orsegment 5l toward the locking-lug 78, applying pressure to that otherear 28 which is interposed between the lockving-lug and thebolt-operating lug, and hence carrying the locking-lug forward inadvance of the ear 28.

Should it be desirable to secure both knobs against operation, it isonly necessary to withdraw the locking-slide 77 to occupy a secondadjusted position, wherein the lug 78, while still in the path of theadjacent ear 28 of the bolt-yoke, also engages alock-notch 8l in theadjacent slot of the lock-casing. Obviously the sleeve cannot be turnedwithout disengaging the lug 78 from the notch 8l, the barrel cannot beturned without communicating motion to the sleeve, and the bolt cannotbe repressed independently of the knobs, as by an instrument insertedinto the catch or bolt socket of the door or frame. Thus when the slideis in its first adjusted position the outer knob is locked againstmovement irrespective ot' the tumblers, while the inner knob is free tobe operated to withdraw the bolt, and when the locking-slide is in itssecond adjusted position both knobs and the bolt are locked positivelyagainst movement. To secure the slide in either of its adjustedpositions, Iemploy a catch 82, consisting of a spring provided with adouble-faced nose for engagement with either of a series of seats ornotches formed iu the under or inner side of the slide. Obviously theadjustment of the slide may be accomplished without any specialmanipulatiou of the catch, the doublebeveled nose of the latter allowingthe slide to be adjusted in opposition to the resistance offered by thecatch, while the latter maintains the slide after adjustment againstaccidental displacement.

The operation and advantages of my improved lock, particularly inconnection with the outer or tumbler-locked knob, which may be releasedand turned by the same hand of the operator, will be readily understoodfrom the foregoing description, and, furthermore, it will be obviousthat various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.
